The author argues that while advances in technology may have made long-range and long-term planning less critical, they have not made long-run decisionmaking obsolete.     

Store environment and consumer purchase behavior: Mediating role of consumer emotions

This article presents a large-scale cross-sectional field study of the effect of store environment on consumer emotions and the resulting influence on aspects of consumer behavior with actual shopping behavior used as an example. Cast into a stimulus–organism–response framework, the results suggest that a consumer's emotions can be a mediating factor in the purchase process. In this study, we identify and explore how store environment and emotional states may influence various dimensions of purchase behavior. This research confirms that although cognitive factors may largely account for store selection and for most planned purchases within the store, the environment in the store and the emotional state of consumers may be important determinants of purchase behavior. This research has many pragmatic applications, because pleasure was associated with the amount of money spent and affinity for the store, whereas arousal was associated with money spent in the store, time spent in the store, and the number of items purchased in the store. © 1997 John Wiley & Sons, Inc.     

Efficiency tests in the Spanish futures markets

The Spanish futures markets, the MEFF RENTA FIJA, and the MEFF RENTA VARIABLE, are among the fast-growing futures markets in the world. These markets are known for their cutting-edge technological innovations related to trading, providing information, clearing, and settlement. The growing importance of these markets for both foreign and domestic investors motivated the examination of their efficiency. Test results from serial correlations, unit root tests, and variance ratio tests overwhelmingly show that the random walk hypothesis cannot be rejected, indicating that the MEFF markets are efficient. © 1999 John Wiley & Sons, Inc.

Comparing post-operative resource consumption following transcatheter aortic valve implantation (TAVI) and conventional aortic valve replacement in the UK

Objective:

To define the in-hospital and 6-month post-discharge resource use, following Transcatheter Aortic Valve Implantation (TAVI) and conventional Aortic Valve Replacement (AVR) surgery within a single UK hospital.

Methods:

A local service evaluation of patients undergoing TAVI or AVR between January 2011 and May 2012 captured data until 6-months post-procedure, collected from hospital records and via a General Practitioner questionnaire. The main end-points were mortality, time in ITU/HDU, hospital length of stay (LoS), discharge destination, re-admission, and post-discharge primary/secondary care resource use. Sub-group analyses were performed for AVR patients aged ≥80 (AVR?≥?80) and with EuroSCORE of ≥10 (AVR ES?≥?10) to allow more direct comparison with ‘TAVI type’ patients.

Results:

Results are given as means (standard deviation) for TAVI (n?=?51), AVR (n?=?188), AVR?≥?80 (n?=?48), and AVR ES?≥?10 (n?=?47), respectively, unless otherwise stated. Age in years was 83.0 (8.1), 71.2 (13.1), 84.1 (2.7), 79.4 (7.1); EuroSCORE was 24.7 (11.9), 8.1 (6.4), 12.0 (6.0), and 16.5 (6.6); post-operative LoS (days) was 11.5 (11.2), 10.9 (10.8), 14.3 (16.7), and 15.2 (17.7). For discharged patients, 0%, 7%, 13%, and 9% had unplanned cardiac-related re-admissions within 30-days of discharge. Time to first readmission was 74.6 (34.0), 35.0 (34.2), 20.8 (9.7), and 22.6 (14.3) days.

Limitations:

This was a single-center retrospective evaluation, not prospectively powered to confirm differences in outcomes.

Conclusions:

Despite TAVI being performed in an older, higher risk population, LoS was similar to AVR. Most strikingly there were no cardiac-related re-admissions within 30-days for TAVI and time to first re-admission was significantly longer. This evaluation suggests that TAVI is clinically appropriate and provides economic advantages in both the hospital and post-discharge setting in this high risk group. Many patients undergoing TAVI are considered unfit for surgery and, hence, TAVI offers a treatment that delivers similar results to traditional AVR without the high risk associated with surgery.     

Optimal Entrepreneurial Financial Contracting

This paper studies the optimal financing (capital structure) of entrepreneurial activity in the context of risk-aversion by incorporating the deadweight costs of bankruptcy and taxes. Unlike the extreme debt ratio (corner solution) predicted by scholars using linear models, this paper provides unique interior results for risk-free as well as risky debt, irrespective of corporate taxes. The paper also shows the necessary and sufficient conditions for both forms of debt, and the pareto-optimality of one over the other. The important findings of this paper are: (i) the existence of an equilibrium, where the borrowing interest rate is greater than the lending rate, despite the violation of Fisher separation theorem (1930); (ii) wealth plays a critical role in determining the debt ratio and the equilibrium risk-free rate of interest, complementing the De Meza and Webb (1987 and 1999) studies; (iii) an explanation for the preferred stock and income bond puzzles, extending Fooladi et al. (1991) and McConnell and Schlarbaum (1991).     

Where is the Security Blanket? Developing Social Media Marketing Capability as a Shield from Perceived Cybersecurity Risk

Although cybersecurity is important for any organization, firms have little understanding of the ramifications of perceived cybersecurity risk and how marketers can avert its negative marketing outcomes. The inability of firms to prevent massive data breaches in the recent past has heightened cybersecurity risk perceptions of customers and cybersecurity-related marketing challenges and opportunities. This study links cybersecurity risk with firm risk through firm reputation by developing a conceptual framework grounded in perceived risk theory in conjunction with dynamic capabilities and social network theoretical perspectives. Our findings show that social media marketing capabilities enable firms in mitigating the adverse impact of cybersecurity risk in declining firm reputation and value. Thus, this study provides significant implications for marketing theory and practice.     

Determinants of Trade Costs and Trade Growth Accounting between India and the European Union during 1995–2010

This study aimed to utilise the micro‐founded measure of trade cost derived by Novy to estimate the relative bilateral trade costs of India with its European Union partners. The advantage of using such a model is that the trade costs can be derived entirely using observable trade data. The results show that Indian tariff equivalent with its major EU trading partners has declined by 20 percentage points between 1995 and 2010, with Malta and Latvia experiencing the greatest decline. The study then decomposes the bilateral trade growth to ascertain whether it is an outcome of increased domestic production or reduction in bilateral and multilateral trade barriers. Novy's model indicates that the decline in relative bilateral trade costs explains the greatest percentage of this trade growth, which is partially offset by decline in multilateral resistance terms that has diverted trade away to other trading partners primarily in South and South‐East Asia and North America.
